AI Technical Summary

Benefits of technology

This patent describes an improved folding knife that solves previous problems. It features a blade that can be moved between a closed position and an open position. There is a liner lock element that can be locked or unlocked to prevent or enable movement of the blade. There is also a safety element that can be engaged or disengaged to control the liner lock element. Overall, this design allows for safer and easier use of folding knives.

Problems solved by technology

A serious disadvantage of liner lock folding knives is that inadvertent movement of the liner, or extreme force exerted upon the blade, can cause the blocking portion of the liner to be dislodged from the notch on the blade's tang, enabling the blade to close unintentionally.
Inadvertent closure of the blade could lead to serious injury to the user.

Embodiment Construction

[0013]An embodiment of the folding knife of the present invention is shown and generally designated by the reference numeral 10.

[0014]FIGS. 1-5 illustrate the improved folding knife 10 of the current invention. More particularly, the folding knife has an elongated handle 12 having a right liner 14 and a left liner 16. The right liner is a planar body having a front 18, rear 20, exterior 22, interior 24, top 26, bottom 28, and a peripheral profile. The exterior and interior are opposed major faces. The bottom front of the right liner defines a finger recess 30 that accommodates the user's index finger when the knife is held in the fully opened position. The front of the right liner defines a pivot aperture 32. The top middle of the right liner defines a slot 34. A portion of the right liner just in front of the finger recess that defines a rear portion of the slot is a block portion / lock bar 36. Thus, the right liner can be viewed as a liner lock element. The lock bar is a leaf sprin...

Abstract

A folding knife has an elongated blade having a pivot end and an opposed free end, the pivot end of the blade pivotally connected to a handle, the blade being movable between a closed position in which the blade is protectively received by the handle and an open position in which the blade extends away from the handle, a liner lock element connected to the handle and having a block portion, the liner lock element movable between a locked position in which the block portion operably contacts a portion of the pivot end of the blade to prevent movement of the blade from the open position to the closed position, and an unlocked position in which movement of the blade from the open position to the closed position is enabled, and a safety element movable between an engaged position and a disengaged position.

Description

FIELD OF THE INVENTION[0001]The present invention relates to knives, and more particularly to a folding knife that features a liner lock with a secondary safety that when engaged makes the liner lock enormously resistant to shock and impact.BACKGROUND OF THE INVENTION[0002]Liner lock knives are a popular style of folding pocket knives. “Liner lock” refers to a blade locking mechanism, which is a side-spring detent lock that can be opened and closed with one hand without repositioning the knife. The liner lock's lock bar abuts the tang of the blade in the open position to prevent the blade from closing. To release the lock, the user presses the lock bar back toward the handle side, which shifts the lock bar out of the way, enabling the blade to close. In the closed position, the lock bar rests alongside the handle and the blade, typically employing a ball detent to releasably secure the blade in the closed position. A serious disadvantage of liner lock folding knives is that inadvert...
